16# SMP OPTIONS:
17#
18# The apic device enables the use of the I/O APIC for interrupt delivery.
19# The apic device can be used in both UP and SMP kernels, but is required
20# for SMP kernels. Thus, the apic device is not strictly an SMP option,
21# but it is a prerequisite for SMP.
22#
23# Notes:
24#
25# HTT CPUs should only be used if they are enabled in the BIOS. For
26# the ACPI case, ACPI only correctly tells us about any HTT CPUs if
27# they are enabled. However, most HTT systems do not list HTT CPUs
28# in the MP Table if they are enabled, thus we guess at the HTT CPUs
29# for the MP Table case. However, we shouldn't try to guess and use
30# these CPUs if HTT is disabled. Thus, HTT guessing is only enabled
31# for the MP Table if the user explicitly asks for it via the
32# MPTABLE_FORCE_HTT option. Do NOT use this option if you have HTT
33# disabled in your BIOS.
34#
35# IPI_PREEMPTION instructs the kernel to preempt threads running on other
36# CPUS if needed. Relies on the PREEMPTION option

71# Options for CPU features.
72#
73# CPU_ATHLON_SSE_HACK tries to enable SSE instructions when the BIOS has
74# forgotten to enable them.
75#
76# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
77# CPU if CPU supports it. The default is double-clock mode on
78# BlueLightning CPU box.
79#
80# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
81# BlueLightning CPU. It works only with Cyrix FPU, and this option
82# should not be used with Intel FPU.
83#
84# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
85#
86# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
87# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
88# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
89#
90# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct
91# mapped mode. Default is 2-way set associative mode.
92#
93# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables
94# reorder). This option should not be used if you use memory mapped
95# I/O device(s).
96#
97# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32
98# machines. VmWare 3.x seems to emulate this instruction poorly, causing
99# the guest OS to run very slowly. This problem appears to be fixed in
100# VmWare 4.x, at least in version 4.5.2, so that enabling this option with
101# VmWare 4.x will result in locking operations to be 20-30 times slower.
102# Enabling this with an SMP kernel will cause the kernel to be unusable.
103#
104# CPU_DISABLE_SSE explicitly prevents I686_CPU from turning on SSE.
105#
106# CPU_ELAN enables support for AMDs ElanSC520 CPU.
107# CPU_ELAN_PPS enables precision timestamp code.
108# CPU_ELAN_XTAL sets the clock crystal frequency in Hz.
109#
110# CPU_ENABLE_LONGRUN enables support for Transmeta Crusoe LongRun
111# technology which allows to restrict power consumption of the CPU by
112# using group of hw.crusoe.* sysctls.
113#
114# CPU_FASTER_5X86_FPU enables faster FPU exception handler.
115#
116# CPU_GEODE is for the SC1100 Geode embedded processor. This option
117# is necessary because the i8254 timecounter is toast.
118#
119# CPU_I486_ON_386 enables CPU cache on i486 based CPU upgrade products
120# for i386 machines.
121#
122# CPU_IORT defines I/O clock delay time (NOTE 1). Default values of
123# I/O clock delay time on Cyrix 5x86 and 6x86 are 0 and 7,respectively
124# (no clock delay).
125#
126# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
127# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
128# The default value is 5.
129#
130# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
131# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
132# 1).
133#
134# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
135# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
136# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.
137#
138# CPU_RSTK_EN enables return stack on Cyrix 5x86 (NOTE 1).
139#
140# CPU_SOEKRIS enables support www.soekris.com hardware.
141#
142# CPU_SUSP_HLT enables suspend on HALT. If this option is set, CPU
143# enters suspend mode following execution of HALT instruction.
144#
145# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
146#
147# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
148# K5/K6/K6-2 CPUs.
149#
150# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
151# flush at hold state.
152#
153# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
154# without cache flush at hold state, and (2) write-back CPU cache on
155# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
156#
157# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
158# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
159# executed. This option is only needed if I586_CPU is also defined,
160# and should be included for any non-Pentium CPU that defines it.
161#
162# NO_MEMORY_HOLE is an optimisation for systems with AMD K6 processors
163# which indicates that the 15-16MB range is *definitely* not being
164# occupied by an ISA memory hole.
165#
166# NOTE 1: The options, CPU_BTB_EN, CPU_LOOP_EN, CPU_IORT,
167# CPU_LOOP_EN and CPU_RSTK_EN should not be used because of CPU bugs.
168# These options may crash your system.
169#
170# NOTE 2: If CYRIX_CACHE_REALLY_WORKS is not set, CPU cache is enabled
171# in write-through mode when revision < 2.7. If revision of Cyrix
172# 6x86 >= 2.7, CPU cache is always enabled in write-back mode.

236# DEVICE_POLLING adds support for mixed interrupt-polling handling
237# of network device drivers, which has significant benefits in terms
238# of robustness to overloads and responsivity, as well as permitting
239# accurate scheduling of the CPU time between kernel network processing
240# and other activities. The drawback is a moderate (up to 1/HZ seconds)
241# potential increase in response times.
242# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
243# to achieve smoother behaviour.
244# Additionally, you can enable/disable polling at runtime with help of
245# the ifconfig(8) utility, and select the CPU fraction reserved to

770# 0x0020 Statclock is broken.
771
772# Notes on the Specialix SI/XIO driver:
773# The host card is memory, not IO mapped.
774# The Rev 1 host cards use a 64K chunk, on a 32K boundary.

776# The cards can use an IRQ of 11, 12 or 15.
777
778# Notes on the Sony Programmable I/O controller
779# This is a temporary driver that should someday be replaced by something
780# that hooks into the ACPI layer. The device is hooked to the PIIX4's
781# General Device 10 decoder, which means you have to fiddle with PCI
782# registers to map it in, even though it is otherwise treated here as
783# an ISA device. At the moment, the driver polls, although the device
784# is capable of generating interrupts. It largely undocumented.
785# The port location in the hint is where you WANT the device to be
786# mapped. 0x10a0 seems to be traditional. At the moment the jogdial
787# is the only thing truly supported, but apparently a fair percentage

78# BlueLightning CPU box.
79#
80# CPU_BLUELIGHTNING_FPU_OP_CACHE enables FPU operand cache on IBM
81# BlueLightning CPU. It works only with Cyrix FPU, and this option
82# should not be used with Intel FPU.
83#
84# CPU_BTB_EN enables branch target buffer on Cyrix 5x86 (NOTE 1).
85#
86# CPU_CYRIX_NO_LOCK enables weak locking for the entire address space
87# of Cyrix 6x86 and 6x86MX CPUs by setting the NO_LOCK bit of CCR1.
88# Otherwise, the NO_LOCK bit of CCR1 is cleared. (NOTE 3)
89#
90# CPU_DIRECT_MAPPED_CACHE sets L1 cache of Cyrix 486DLC CPU in direct

92#
93# CPU_DISABLE_5X86_LSSER disables load store serialize (i.e., enables

95# I/O device(s).
96#
97# CPU_DISABLE_CMPXCHG disables the CMPXCHG instruction on > i386 IA32

99# the guest OS to run very slowly. This problem appears to be fixed in
100# VmWare 4.x, at least in version 4.5.2, so that enabling this option with

126# CPU_L2_LATENCY specifies the L2 cache latency value. This option is used
127# only when CPU_PPRO2CELERON is defined and Mendocino Celeron is detected.
128# The default value is 5.
129#
130# CPU_LOOP_EN prevents flushing the prefetch buffer if the destination
131# of a jump is already present in the prefetch buffer on Cyrix 5x86(NOTE
132# 1).
133#
134# CPU_PPRO2CELERON enables L2 cache of Mendocino Celeron CPUs. This option
135# is useful when you use Socket 8 to Socket 370 converter, because most Pentium
136# Pro BIOSs do not enable L2 cache of Mendocino Celeron CPUs.

144#
145# CPU_UPGRADE_HW_CACHE eliminates unneeded cache flush instruction(s).
146#
147# CPU_WT_ALLOC enables write allocation on Cyrix 6x86/6x86MX and AMD
148# K5/K6/K6-2 CPUs.
149#
150# CYRIX_CACHE_WORKS enables CPU cache on Cyrix 486 CPUs with cache
151# flush at hold state.
152#
153# CYRIX_CACHE_REALLY_WORKS enables (1) CPU cache on Cyrix 486 CPUs
154# without cache flush at hold state, and (2) write-back CPU cache on
155# Cyrix 6x86 whose revision < 2.7 (NOTE 2).
156#
157# NO_F00F_HACK disables the hack that prevents Pentiums (and ONLY
158# Pentiums) from locking up when a LOCK CMPXCHG8B instruction is
159# executed. This option is only needed if I586_CPU is also defined,
160# and should be included for any non-Pentium CPU that defines it.

413# 0x02 don't use the npx registers to optimize bzero.
414# 0x04 don't use the npx registers to optimize copyin or copyout.
415# The npx registers are normally used to optimize copying and zeroing when
416# all of the following conditions are satisfied:
417# I586_CPU is an option
418# the cpu is an i586 (perhaps not a Pentium)
419# the probe for npx0 succeeds
420# INT 16 exception handling works.
421# Then copying and zeroing using the npx registers is normally 30-100% faster.
422# The flags can be used to control cases where it doesn't work or is slower.
423# Setting them at boot time using hints works right (the optimizations
424# are not used until later in the bootstrap when npx0 is attached).
425# Flag 0x08 automatically disables the i586 optimized routines.

779# This is a temporary driver that should someday be replaced by something
780# that hooks into the ACPI layer. The device is hooked to the PIIX4's
781# General Device 10 decoder, which means you have to fiddle with PCI

783# an ISA device. At the moment, the driver polls, although the device
784# is capable of generating interrupts. It largely undocumented.
785# The port location in the hint is where you WANT the device to be
786# mapped. 0x10a0 seems to be traditional. At the moment the jogdial

1151# script understands that it doesn't need to load the `streams' module under
